I have a aluminum airbox with a K&N air filter with no lid. my jetting is 155L/160R with the fuel screw's 2 1/2 turns out. plus i have vito's jet kit it has everything you need in the kit to jet your carbs.TMC.
What type of airbox are u running?
I have a pair of LTR duals coming, so i was thinking what would be the best setup for the duals?
My 660 is stock at the current moment.
